PATRICK P. STACK, OF SALT LAKE CITY, UTAH.

AUTOMATIC I-IOSE-REGULATING LAWN-SPRINKLER AND ADJUSTABLE SUPPORT.

To all whom it may concern:

Be it known that I, PATRICK P. STACK, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Automatic Hose-Regulating Lawn-Sprinklers and Adjustable Supports, of which the following is a specification.

This invention relates to automatic sprinklers and has for its object the provision of a comparatively simple and thoroughly efiicient device of this character, capable of being readily attached to a garden hose or the like, and which will cause the water to be discharged therefrom either in a solid stream or in the form of a spray.

A further object is to provide a lawn sprinkler, the construction of which is sucn that the hose will automatically adjust itself to the variations in water pressure without overturning the sprinkler or otherwise displacing the same.

A further object is to provide a sprinkler including an adjustable support having a spraying plate or tongue pivotally mounted thereon and provided with a swiveled bearing ring adapted to receive the nozzle of a hose so as to permit said nozzle to rotate in the bearing ring and to be swung laterally on either side of the spraying plate.

A further object is to provide means whereby the spraying plate may be adjusted at any angle or inclination with respect to the hose so as to direct the stream or spray in difierent directions, and means for clamping the spraying plate in adjusted position.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and. accompanying drawings, in which:

Figure 1 is a perspective view of an automatic lawn sprinkler constructed in accordance with my invention; Fig. 2 is a Specification of Letters Patent.

longitudinal sectional view of the same; Fig. 3 is a top plan view, showing in dotted lines, the manner of tilting the nozzle to one side of the spraying plate when it is desired to discharge a solid stream fro-m the hose; Fig. 4 is a transverse sectional view, showing the manner of clamping the spraying plate in ad usted position; Fig. 5 1s a side elevation, showing the adjustable support in lowered position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved lawn sprinkler forming the subject matter of the present invention comprises an adjustable support 5, preferably formed of a single length of wire having an intermediate portion thereof bent upon itself to produce oppositely disposed down-' i wardly inclined supporting feet 6, the wire being thence extended upwardly to form spaced parallel arms 7, one of which terminates in an eye 8, while the metal forming the end of the mating arm is bent at right angles thereto and extended through the eye 8 to form a transverse bar 9.

Pivotally mounted on the bar 9, is a spraying plate or tongue 10, preferably formed of a single sheet of flat metal, one end of which is deflected upwardly at 11, while the other end thereof is bent or coiled in the opposite direction to form a transverse loop 12 for the reception of the bar 9, said loop being interposed between the arms 7 so as to cen-' engagement with the bearing ring 13, the

free end of the nozzle having a reduced bore to increase the velocity of the water and having its exterior wall threaded at 18 for engagement with a clamping nut 19, which latter bears against the ring 13 and serves to hold the nozzle in position on the spraying plate.

The bearing ring 13 is provided with a pin 20 which extends through an opening in the spraying plate or tongue 10 so as to form in effect a swivel connection between the bearing ring and plate, thus to permit said bearing ring, together with the nozzle, to be swung laterally and thus direct the stream of water on either side of the spraying plate, as desired.

The wire forming the free end of the arm 9 is extended longitudinally through the eye 8 and provided with threads for engagement with a correspondingly threaded wing nut 21, there being a washer 22 interposed between the eye 8 and adjacentface of the wing nut 21 so that after the spraying plate has been adjusted at the desired angle or inclination wit-h respect to the support 5, said plate may be readily secured in adjusted position by rotating the wing nut.

The deflected end 11 of the plate 10 is disposed in the path of the water from the spraying nozzle so that the impact of the water on the flat face 11 of the plate will spread or spray the water and uniformly distribute the latter over a relatively large area.

In using the device, the nozzle 14 is connected with the male coupling on the end of the hose 15, after which the wing nut 21 is released and the spraying plate 10 adjusted at the desired angle or inclination with respect to the support, the wing nut 21 being subsequently tightened so as to hold said plate in adjusted position, as before stated.

It will here be noted that the wing nut 21 not only serves to hold the arms 7 of the support in proper position, but also serves to clamp the spraying plate or tongue between said arms. It will also be noted that by reason of the fact that the bearing ring 13 is swiveled on the spraying plate 10 and the nozzle 14 loosely mounted in said ring, said nozzle, together with the hose, is free to rotate or swing laterally 011 either side of the plate, thus to automatically adjust the hose to the variations in water pressure without tipping over the support :5 or otherwise accidentally displacing the same.

If a solid stream is desired, it is merely necessary to swing the nozzle to either side of the spraying plate, and if a spray is desired, as for instance, when sprinkling lawns, the volume of water from the nozzle is directed on the deflected end of the plate 10, which latter may be adjusted vertically with respect to the bar 9 so as to throw the water at any desired elevation, as before stated.

The device is extremely simple in construction and may be manufactured and placed on the market at a comparatively small cost.

Having thus described the invent-ion, what is claimed as new is:

1. A device of the class described including a support, a spraying plate pivotally mounted for Vertical tilting movement on the support, a bearing ring pivotally mounted on the plate, a nozzle journaled in the bearing ring, and means for securing the spraying plate in different positions of adjustment.
